Property Value

A collection of AnnLabels to render on top of this AnnContainer.

The labels will be rendered using the global AnnRenderingEngine.ContainerLabelRenderer object. This object is automatically created by the annotation framework and can be usable right away.

The container labels can be used to place text items on top of the container that are not part of the annotations objects. For example, to place legends in a mapping application.
